तर्क आहे:

1ली संख्या × 7 - 8 = दुसरी संख्या

1. 21 ∶ 139 → 21 × 7 - 8 = 147 - 8 = 139

2. 25 : 167 → 25 × 7 - 8 = 175 - 8 = 167

3. 15 : 197 → 15 × 7 - 8 = 105 - 8 = 97 ≠ 197

4. 27 : 181 → 27 × 7 - 8 = 189 - 8 = 181

पर्याय 3 वगळता, सर्व पर्याय दिलेल्या तर्कानुसार आहेत. अशा प्रकारे पर्याय 3 विसंगत  आहे.

म्हणून, '15 : 197 ' ही विसंगत संख्या-जोडी आहे.
